The function needed is to calculate the equal monthly installment of an amortized loan using actual days of month and 365 days in year! Payment is due on the end of each period.
 
JerryKlmns,

I have never seen all of what you are looking for in a single excel function.

I do have an amortization schedule excel wksht that I would share with you but that presents a dilema. I do have a gmail account.

rvnguy,

I end up using

Interest(i)=RemainingCapital(i)*IntRate*ActualMonthDays(i)/365
CapitalPaid(i)=Installment(i)-Interest(i)
RemainingCapital(i+1)=RemainingCapital(i)-CapitalPaid(i)
Installment(i+1)=Installment(i)
RemainingCapital(0)=Loan Capital

and goal seek to set Sum(CapitalPaid(i))= Loan Capital by changing cell of Installment(i) and adjusting last installment to deal with rounding...

Schedule dates are taking care of this (29/Feb/200x),fine

Are there any thoughts or suggestions you could share?
Or have you a different way ??
